Abstract
The fire assay technique is the oldest and most reliable method used to determine
gold karat, because of the destruction of gold into pieces and the long time which
spent at analyzing; a well powerful for nondestructive analytical analyzer had took it
place, it is x-ray fluorescence spectroscopy (XRF) that we used to analysis gold
specimens. It is fast and accuracy technique, XRF can provide qualitative and
quantitative analysis regarding the thickness of the tested material by measuring the
intensity and characteristic energy of the emitted x-rays.
The present work explained the analyzing of eleven specimens of gold bullions and
jewelry at XRF laboratory in Sudanese standard and metrology organization
(SSMO). As a result of x-ray fluorescence analysis; only three alloys were observed
in XRF spectrum of all gold samples, gold metal, silver and copper metal with
different ratios which calculated by stocks instead of gram, a pure gold piece 24
karat includes 1000 stocks of gold, also three different gold karats were determined
jewelry testing: 21 gold karat which contain about 875 stock of gold, 18 gold karat
has 750 stock of gold, 14 gold karat has 580 stock. Alloys values were recorded for all specimens.
